The Link widget is a hyperlink to the specified URL.
This is the location the widget redirects to when clicked.
The icon type lets you set the foreground to common brand icons, available from Iconify. Once this type is selected, click the Foreground Icon button to show the list of icons to choose from.
The image type lets you set an image to the foreground. Once this type is selected, use the Foreground Image File Input to add an image.
The letter type lets you set a letter, or group of letters, to the foreground. Once this type is selected, use the Foreground Letter text field to set the letters.
This is the color of the background that shows up behind all of the foreground types.
This is the color of the foreground for either the icon or letter; it does not affect the image type.
This is the container (or none) that the url will be opened in. See more info on Firefox Multi-Account Containers here.
If checked, clicking on the widget will open up in a new tab instead of replacing the current tab.
